Case Study: UNTUCKit unifies SMS and email to drive lifecycle growth with Attentive

How UNTUCKit Turned SMS and Email into a Lifecycle Growth Engine with Attentive

UNTUCKit, the apparel brand known for its untucked shirts and versatile menswear, needed to fix a fragmented lifecycle marketing setup. Although it had used Attentive for SMS since 2019, its email program lived on a separate ESP, creating siloed journeys, duplicate codes, conflicting triggers, and inconsistent customer experiences across channels.

UNTUCKit migrated email to Attentive and unified SMS and email on the platform, using Attentive’s AI Pro and Identity AI to improve recognition and cross-channel orchestration. The result was a 25% year-over-year increase in revenue from triggered journeys, more than 30% growth in lifecycle-driven revenue within six months, near-60% unique open rates in email journeys, and incremental gains of 15–20% in abandonment programs, with SMS and email working together as a balanced revenue engine.
